Embodiment Construction

[0018] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like figure 1 As shown, the present invention provides a pressure-stabilizing plate relief valve (hereinafter referred to as relief valve). The structure includes a sealing ring 1, a sealing cover 2, a spring 3, a sealing ring 4, a valve body 5, a retaining ring 6, a sealing ring 7, a spring seat 8, an adjusting gasket 9, and a filter screen 10.

[0020] The pressure-stabilizing plate relief valve as a whole is installed in the installation hole of the engine lubricating oil system in a plug-in manner. The system installation hole not only provides installation support for the relief valve, but also provides a medium flow path for the relief valve. The installation hole of the system includes a high-pressure ch...

Abstract

The invention discloses a stable-pressure flat plate overflow valve, and belongs to the technical field of engine lubricating systems. The stable-pressure flat plate overflow valve has the following beneficial effects: 1) a valve body is high in function integration degree, comprises mounting and positioning functions of related parts, and is small in structural size and various in function; 2) the system pressure stabilizing effect is excellent; as a flat plate valve structure is adopted, the influence on the system pressure by hydraulic power is prevented; and during opening of the overflowvalve, the system working pressure cannot fluctuate; and 3) the pollution resistance is high; and a filter screen is arranged in an inlet of the overflow valve to guarantee no blockage of a planar sealing structure.

Description

technical field [0001] The invention belongs to the technical field of engine lubricating systems, and in particular relates to a pressure stabilizing plate relief valve. Background technique [0002] During the working process of the engine, the fuel system needs to adjust the fuel supply of the fuel system according to the different working conditions of the engine. The fuel system is a closed-loop control system, including an actuator and a feedback mechanism. The actuator is the control, and the feedback mechanism is the sealing structure that controls the on-off of the oil circuit. The traditional feedback mechanism mostly adopts the form of linear displacement sensor, which has a complex structure, many parts, and poor reliability. The existing design cannot meet the requirements of rapid response control oil circuit on-off. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is: how t...
